Bacteria Growing Experiments in Petri Plates Introduction. Bacteria are microorganisms that grow everywhere. We can collect and grow them in specially prepared petri dishes. Blood agar or tryptic soy agar with 5% sheep's blood is an excellent medium for supplying bacteria with nutrients and an environment in which we can see them grow.Sterile powdered agar with nutrients can be mixed with water, heated and then poured into empty petri plates or ready-to-use dishes can be purchased.The undigestible agar is a gelatin-like substance with a semi solid surface on which the bacteria can grow while they consume the added nutrients (like sheep's blood).eep growing petri dishes taped closed until your experiment is done. Then you should safely destroy the fuzzy bacteria colonies using bleach. Below are general outlines of three types of experiments involving bacteria growth. They are offered to assist in designing your own experiment or project.

What is the purpose of blood in the blood agar medium? The erythrocytes in blood agar serve two purposes: as a source of food for the growing bacteria and as a diagnostic indicator for certain types of bacteria.There are two types of red blood cell hemolysis, referred to as alpha (or complete) hemolysis and beta (or incomplete) hemolysis.The presence of alpha or beta hemolysis on a blood agar plate is diagnostic for certain types of bacteria.he erythrocytes in blood agar serve two purposes: as a source of food for the growing bacteria and as a diagnostic indicator for certain types of bacteria.

"""Tsa Plates Microbiology"" Essays and Research Papers" DIFFERENT TYPES OF AGAR Mac Conkey‘s Agar plate MacConkey (also McConkey) agar is a culture medium designed to grow Gram-negative bacteria and stain them for lactose fermentation. It contains bile salts (to inhibit most Gram-positive bacteria, except Enterococcus and some species of Staphylococcus), crystal violet dye (which also inhibits certain Gram-positive bacteria), neutral red dye (which stains microbes fermenting lactose), lactose and peptone.

Microbiology Tests Mannitol Salt Agar. Mannitol provides the substrate for fermentation and makes the medium differential. The salt makes the medium selective because its concentration is high enough to dehydrate and kill most bacteria. Staphylococci thrive in the medium largely because of their adaptation to salty habitants, such as human skin.

What Is the Purpose of the Nutrient Agar? Quick Answer. Agar is a mixture used in laboratories to culture microbes. It contains a mixture of nutrients including agar, yeast or beef extract, salt and peptides. The nutrient rich mixture allows microbes to grow quickly and in isolation, aiding in the identification and classification of micro-organisms and the diagnosis of infections.

- The growth of Gram negative organisms on this medium tends to be stunted or completely halted. Blood Agar (5% sheeps blood- TSA plates) is a nutritive medium with differential properties in respect to hemolysis. Hemolysis is the destruction of erythrocytes (RBCs). The degree to which the erythrocytes are destroyed can be recognized by the effects of hemolytic enzymes on the cells in the medium. Complete breakdown of the RBCs is termed beta (β) hemolysis and is recognized by clearing around the colonies creating the hemolysin.
